Isingeniso
Izinsimbi ezingenasici zaziwa njengezinsimbi ezinengxubevange ephezulu.Ahlanganisa cishe u-4-30% we-chromium.Zihlukaniswa zibe izinsimbi ze-martensitic, austenitic, ne-ferritic ngokusekelwe kusakhiwo sazo se-crystalline.
I-Grade 317 insimbi engagqwali inguqulo eguquliwe yensimbi engagqwali engu-316.Inamandla aphezulu kanye nokumelana nokugqwala.Iminingwane elandelayo inikeza imininingwane eyengeziwe mayelana ne-grade 317 yensimbi engagqwali.

Ukwenziwa kanye Nokwelashwa Kokushisa
Ukusebenziseka kalula
Ingabe ufuna okokusebenza ukuze uhlaziye izinsimbi zakho?
I-Grade 317 insimbi engagqwali iqinile kunensimbi engagqwali engu-304.Kunconywa ukusebenzisa ama-chip breakers.Ukuqina kwaleli ngxube kuzoncishiswa uma kusetshenziswa ukudla okungaguquki kanye nesivinini esiphansi.
Ukushisela
Ibanga 317 insimbi engagqwali ingashiselwa kusetshenziswa izindlela zokuhlanganisa nezindlela zokumelana.Indlela yokushisela i-Oxyacetylene ayikhethwa kule alloy.I-AWS E/ER317 noma i-317L yensimbi yokugcwalisa ingasetshenziswa ukuthola umphumela omuhle.
Kuyashisa Ukusebenza
Ibanga 317 insimbi engagqwali ingashiswa kusetshenziswa zonke izinqubo ezijwayelekile zokusebenza ezishisayo.Ishisiswe ku-1149-1260°C (2100-2300°F).Akufanele ishiswe ngaphansi kuka-927°C (1700°F).Ukukhishwa kwe-anneal yangemva komsebenzi kungenziwa ukuze kugcinwe isakhiwo esimelana nokugqwala.
Ukusebenza Okubandayo
Ukunyathela, ukugunda, ukudweba, kanye nesihloko kungenziwa ngempumelelo.Ukukhishwa kwe-post-work annealing kwenziwa ukuze kuncishiswe ingcindezi yangaphakathi.
